无位置传感器开关磁阻电机的无反转起动研究

提出了一种检测无位置传感器开关磁阻电机 (SRM )起动前转子初始位置的电流定位法 ,即同时向电机两相以上的绕组注入一定幅度的测试脉冲 ,利用各相测试电流与定子电感和转子位置的关系确定转子初始位置以及相应初始导通相 ,从而实现转子处于任何位置时的无反转起动 ,对不允许转子反转的某些应用场合具有较大的实用价值。

Start Exploration of Position Sensorless SRM without Rotor reversing

A current positioning method is proposed,which detects the rotor initial position and decides the initial starting phase through the relationship of the rotor position,stator winding inductance and testing currents from the injected testing pulse into over two phases of SRM.And the start of position sensorless SRM without reversing can be achieved,which means SRM can be practicable in some reversing forbidden applications.
